how ?

one day,just it was about 12 o'clock ,a police officer was sitting at his desk looking at a small piece of paper,he seemed to be really puzzled,you wanna know why ? ,let me tell you ... because the paper only had the letters "mr" on it ,it was the words written by an old man in the famous street "lost" , it was actually called that last night only,let me tell you what happened,just about the same time at night ,an old man was in front of his t.v drinking his cup of coffee"as he actually used to" ,and he suddenly heard someone screaming outside ,but that didn't seem to bother him,as it was his favorite television program ,but after the program was finished,he looked out of his window to check out what had happened,but he actually didn't see anybody out there! ,"then,what was that screaming for?"wondered the old man,but it was actually mysterious because when he looked around,he found no people,and when he looked a little bit close,he found no buildings,and after he had put on his glasses ,he found out there was no street out there :) ,his building was completely lonely ,and he then heard a knock on the door,the old man took his knife and stayed cautious but didn't open the door,that wasn't useful anyway,because someone entered and then ,both the man and the building were no longer there,either . and just right before that happened,the man left a paper out of the building with the two letters "mr" ,i wish it wasn't a story i have to finish,just to keep you surprised :p ,but then the police officer who was actually called "raphael" ,that man went to the place where the street was,and he didn't know what to do as the street was no longer there
